I keep a colony of 4 in a 29 gallon high with about 3 inches of water, cork bark flats and pothos. Surprisingly they are actually cleaner than any other species I keep. That may be due all the tannins in the water though. I also added a tiny pump to maintain water circulation. As the group has matured over the past year and a half I’ve noticed they are much bolder as well. Initially they were almost impossible to find in the vivarium and were almost always submerged. Now I see them out all the time and they’ll feed pretty aggressively. Keep me posted on how yours progress. Very few people keep any theleoderma species and more information and husbandry notes are always in need. And by all means welcome to the forum!
